摘要:
Disclosed herein is an apparatus and method for continuously producing and dehydrating gas hydrates. The apparatus includes a gas source, a water source, a reactor, a spinning wheel, and a centrifugal separator. The gas source and the water source are connected to the reactor. Gas and water are respectively supplied from the gas source and the water source into the reactor and react with each other in the reactor to form gas hydrate slurry. The spinning wheel and the centrifugal separator are provided in the reactor. The spinning wheel supplies the formed gas hydrate slurry to the centrifugal separator. The centrifugal separator dehydrates the gas hydrate slurry. Water removed from the gas hydrate slurry by the dehydration of the centrifugal separator is re-supplied into the reactor.

A double helix gas hydrate reactor is disclosed. The reactor includes an inlet port (510) into which water and gas are supplied, an outlet port (540) disposed opposite the inlet port, a hollow jacket (580) extending from the inlet port to the outlet port, a hollow outer helix (550) installed in the hollow jacket, and an inner helix (560) installed in the outer helix. The gas and water that are supplied into the inlet port react with each other to form gas hydrate in a channel defined between the inner helix and the hollow jacket.

A character recognition apparatus includes a character display region including a plurality of character buttons, a character output region for displaying characters inputted by using the respective character buttons. The character recognition apparatus further includes a character recognition block for recognizing, when a character button is touched and dragged off to the character output region, a non-display matching character matched with the corresponding character button as an input and displaying the non-display matching character in the character output region. The character display region further includes one or more function key buttons, each being matched with a non-display matching function key, and the character recognition block recognizes, when a function key button is touched and dragged off to the character output region, a non-display matching function key matched with the corresponding function key button as an input.
摘要:
An intermediate service provider operates to mediate communications between mobile terminals and various service providers. In one embodiment, the intermediate service provider and a given mobile terminal establish a persistent session supported by a logical communication channel that is used to convey communications for all of the various service applications implemented by the mobile terminal, i.e., a single, multiplexed channel. In another embodiment, common command subsystems are used to support the multiple service applications, thereby reducing overhead resulting from multiple protocol headers. In yet another embodiment, establishment of communications with various service providers begins with a single connection request message that specifies at least two selected service applications such that the intermediate service provider can establish communications with the multiple service providers in response to the single connection request message.
